A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for receiving a Synchronization Signal Block (SSB) by a user equipment (UE) in a wireless communication system, the method comprising: receiving a SSB comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH); wherein centers of subcarriers for the PSS, the SSS and the PBCH are identical, and wherein the PSS, the SSS and the PBCH are received via a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols and a subcarrier corresponding to the centers of the subcarriers.
2. The method of claim 1 , wherein the SSS is received via an OFDM symbol located between two OFDM symbols in which the PBCH is received.
3. The method of claim 2 , wherein the two OFDM symbols include only the PBCH.
4. The method of claim 2 , wherein the two OFDM symbols comprise Demodulation Reference Signals (DMRSs).
5. The method of claim 4 , wherein the DMRSs are mapped at an equal interval in each of the two OFDM symbols.
6. The method of claim 1 , wherein a number of subcarriers for the PBCH is greater than a number of subcarriers for the PSS and the SSS.
7. The method of claim 1 , wherein a subcarrier spacing for the SSS is identical to a subcarrier spacing for the PBCH.
8. An apparatus for receiving a Synchronization Signal Block (SSB) in a wireless communication system, the apparatus comprising: at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising: receiving a SSB comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH); wherein centers of subcarriers for the PSS, the SSS and the PBCH are identical, and wherein the PSS, the SSS and the PBCH are received via a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols and a subcarrier corresponding to the centers of the subcarriers.
9. The apparatus of claim 8 , wherein the SSS is received via an OFDM symbol located between two OFDM symbols in which the PBCH is received.
10. The apparatus of claim 9 , wherein the two OFDM symbols include only the PBCH.
11. The apparatus of claim 9 , wherein the two OFDM symbols comprise Demodulation Reference Signals (DMRSs).
12. The apparatus of claim 1 , wherein the DMRSs are mapped at an equal interval in each of the two OFDM symbols.
13. The apparatus of claim 8 , wherein a number of subcarriers for the PBCH is greater than a number of subcarriers for the PSS and the SSS.
14. The apparatus of claim 8 , wherein a subcarrier spacing for the SSS is identical to a subcarrier spacing for the PBCH.
15. A user equipment (UE) for receiving a Synchronization Signal Block (SSB) in a wireless communication system, the UE comprising: at least one transceiver; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising: receiving, via the at least one transceiver, a SSB comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH); wherein centers of subcarriers for the PSS, the SSS and the PBCH are identical, and wherein the PSS, the SSS and the PBCH are received via a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols and a subcarrier corresponding to the centers of the subcarriers.
